Release of steam to atmosphere creates noise which is dangerous to plant personnel and is environmentally unacceptable. Steam may be released from either low pressure or high pressure as part of boiler start up system, a bypass vent or a safety relief valve vent system. In each case Baffles Cooling System offers the most economical approach by optimizing silencer design to produce a guaranteed solution through selection of silencer pressure drop and flow velocities appropriate to the duty. Not all steam that is vented is dry, so where there is moisture carried in the steam flow BCS can provide a separator element to remove the excess moisture and prevent this hot liquid from being exhausted out through the vent to fall as hot rain in the area surrounding the vent. The pressure drop across the inlet diffuser is selected according to the duty of the silencer, we can examine the pressure losses through the pipework and recommend the most suitable silencer pressure drop for the vent duty. Silencers may be packed or pack free diffuser only types, depending on the duty requirements. Where a packed silencer is needed the packing material will often be chosen from glass fibre, mineral or ceramic fibre as considered appropriate for the operating conditions. The structural design of the our steam vent silencers are given the same thorough attention as its acoustic design. The external shell is constructed of seamless pipe in smaller sizes and continuously welded rolled plate in larger diameter silencers. Silencers may be mounted horizontally or vertically, pads or cradle type supports are available for easy installation.
